So I’m not understanding how your app started using 22Gb just by browsing your shares. Downloading an actual 22Gb of content would have taken probably close to an hour.
But what I can tell you is that, even if you DELETE stuff that’s downloaded, it does NOT free up the memory.
As you’ve seen, you have to select Clear Cache from the app, which also deletes EVERYTHING from the cache, even files you want to keep downloaded.
It’s one of the most annoying bugs, it’s been reported numerous times by myself and others, and has been around for a LONG time.
But to answer your specific questions, no, nothing is downloaded unless requested.
If you delete it from the DOWNLOADS section of the app, then no, it’s NOT deleted from the cloud.
